BICYCLE-BEARING DUST-PROTECTOR.

SPECIFICATION forming part of Letters Patent No. 674,015, dated May 14, 1901.

Application filed April 26, 1900. Serial No. 14,377- (No model.)

To all whom, it may concern.-

Be it known that I, JOSHUA E. RAGSDALE, a citizen of the United States, residing at Fresno, county of Fresno, State of California, have invented an Improvement in Bicycle-Bearing Dust- Protectors; and I hereby declare the following to be a full, clear, and exact description of the same.

My in vention relates to means for preventing the ingress of dust and the like to ballbearings of bicycles; and it consists of the parts and the construction and combination of parts hereinafter described and claimed.

The figure illustrates the rear axle and adjunctive parts of a bicycle and shows the invention applied thereto.

In the accompanying drawing, A represents the protecting-cap, having an annular flange 5, with a central opening of sulficient diameter to allow the outer end of the axle C to pass through the opening. The end of the axle is screw-threaded and passes through the end of the fork 6 and is secured by a nut 7, with the usually interposed washers.

B is the wheel-hub, having a flange 3, to which the spokes 4 are secured.

Upon the side of the rear wheel of the machine the sprocket-wheel 11, over which the driving-chain passes, is interposed between the spokes 4 and the flange of the cap A. I have therefore shown the flange as formed by the cylindrical portion, which extends at right angles with the face of the sprocket-wheel, and it is thence bent outwardly to form a flat disk-like flange 2, which fits and turns in an annular recessed channel 12, formed in the I claim as new, and desire to secure by Letters Patent, is-

In an improved dust-protector and in combination with an axle,and a wheel-hub mounted thereon, and a sprocket-wheel having a wide annular channel of shallow depth in its face, said wheel mounted on the hub, the protector consisting of a cap having a central opening for the axle, a bent portion inclosing the end of the hub, and a wide vertical flange fitting the channel in the sprocket-wheel but out of direct contact with the inner periphery thereof, the outer face of the flange being substantially flush with the outer face of the sprocket-wheel whereby the overhanging wall of said channel prevents ingress of dust to the hearing.

In witness whereof I have hereunto set my hand.

JOSHUA E. RAGSDALE.
